What is a codon chart

The genetic code is a series of three bases in a row called a codon. Each codon represents and amino acid. For example, the DNA strand AAA-TCT would code for the amino acids lys-ser. You'll need a codon chart to find codons, which can be found online. Hope this helps ! [=

PCR stands for

PCR stands for Polymerase Chain Reaction.

Which type of mutation does not change the amino acids produced

Well consider the substitution of one hydrophillic amino acid for another hydrophillic amino acid. This type of mutation changes nothing but a molecular marker.

or

Silent

What could be a good effect of a mutation

More varity in a population

What sections of DNA are used in DNA fingerprinting

sections that are unique to each person

How are mutations prevented during DNA replication

DNA polymerase checks DNA for errors.
DNA polymerase checks DNA for errors by breaking the hydrogen bonds between the paired nitrogen bases in the DNA molecule. This causes the molecule to separate into two individual strands.

A mutation occurs in the sex cells of a full-grown zebra. The mutation affects the genes responsible for producing blood proteins. What will most likely happen to the zebra

The zebra will have offspring who cannot produce blood proteins.

A scientist wants to be able to artificially produce a protein that is produced in the livers of frogs. The scientist has located all of the mRNA produced by the liver and produced the cDNA. What shou

Mix the cDNA with the liver DNA
